该程序可以用于两个人在LAN/Intranet(或者Internet)上进行视频会议。现在有许多视频会议程序，每个都有各自的性能提升技术。主要的问题是视频会议视频帧的尺寸对于传输来说太大。因此，性能依赖于对帧的编解码。 -the two procedures can be used in LAN/Intranet (or the Internet) for video conferencing. Now there are many video conference proceedings, each have their own performance enhancements. The main problem is video conferencing video frame size too large for transmission. Therefore, the performance depends on the right frame codec.

H.323协议源码开发包，可以很方便地开符合标准的H.323终端或MCU，内容已经过测试-H.323 source development kits, it is easy to open sub-standard H.323 terminals or MCU, which has been tested

VoIP正在arapidly不断发展的技术，可以彻底改变可能的电信业。当wirelessdata网络实施，网络电话可能被证明是有助于收敛ofexisting固定和移动电话网络与快速增长的有线andwireless数据网络。服务的能力andQuality是两个需要无线VoIP的商业部署之前beresolved最重要的问题。本文开头的数据adetailed解释网络与问候网络建模与流量分布在一起。的VoIP，WLAN和VoIP在WLAN已经解释的优势，劣势和实施基于WLAN的VoIP的问题。不同的VoIP传输系统：RTP，RTSP，SIP和H323也进行了审查。一个8节点的移动电话系统hasbeen使用NS2和实验设计已经进行测量thesystem在提供服务的质量方面通过一系列的因素，包括多个节点，包大小和客流率。如延迟，吞吐量和packetlost参数已经测量通过WLAN来评估的VoIP的服务质量。基于一个NS2代码和differentparameters如延迟，吞吐量和数据包丢失的打印输出包括以supportthis论文。
